To creep on someone by watching the Spotify activity feed and noting their taste in music.
I spotispied on Buster's playlists...there are two called "Lucille"...
After spotispying on Maeby for 3 months, George Michael could finally woo her by pretending to coincidentally have the EXACT same taste in music.
Everytime I spotispy on Gob, he is listening to the Final Countdown...over and over again.
